Knife Vise Construction

Great knife-vise I learned about at the American Bladesmith School. Will hold any length blade and allow user to rotate to a preferred angle while working. I have included some measurements from my vise as a starting point. Build according to your own needs.

Inside collar is a 2" diameter by 4.5" long piece of pipe. The screw is a piece of 3/8" by 4.5" all-thread using a 1" diameter by 3" long wood dowel as a handle. A nut is welded on the pipe for the screw to engage. A tiny tab on the back keeps part from slipping out of the outer collar. This tab will pass through the outer collar slot for assembly.

Outside collar is made from a piece of 2.5" diameter pipe about 2.5" long. Cut a ¼" to 3/8" wide slot the length of the pipe. Bottom bar for gripping in a machinist vise is 3/8" by 1.5" by 6" flat bar. The two ears for the clamp screw are ¼" by 1.25" by 2" flat bar. One of the ears has a nut welded to it for the screw to engage. Screw is a piece of 3/8" by 3" all-thread with a 3/16" by ½" by 4" handle.

The wood blocks are 2" diameter by 4.5" long. Cut a 3/8" wide slot out of the center. This will give clearance to hold a blade between the two halves. May need a bit wider slot if you wish to put leather on the blocks plus hold a blade? Inlay an 1/8" by ¾" by 1.25" piece of steel into one wood block for the clamp screw to push on.
